This is a weird conspiracy theory. You'd have to believe that real estate investors were pulling the strings in companies to get them to spend more money with no upside. Like they're just milking these companies for rent and the companies are doing it because they want to give money to the real estate investors?
Even in the rare case where real estate investors are also investors in the startup, my experience is that the startup gets reduced-rate rent as a bonus.
